Currently, Ariel is the only known teacher. Haruna appears to be the 634,526,379th student, while Chris and Kyoko are both former students. Ayumu is also technically accepted as one of the students as he fights as a Masō-Shōjo for Haruna. The Masō-Shōjos are magically-powered girls in cutesy girlish outfits (or in Ayumu's case, a guy in a dress), which grants them more powerful abilities.
